(b) The addition of any switch, control or external connection;
(c) Any modification to provide for additional transmitting frequencies, increased modulation level, a different form of modulation, or increased TP (RF transmitter power expressed in W (watts), either mean power (TP averaged over at least 30 cycles of the lowest modulating frequency, typically 0.1 seconds at maximum power) or peak envelope power (TP averaged during 1 RF cycle at the highest crest of the modulation envelope), as measured at the transmitter output antenna terminals.)
